Abstract
An eye safety system, based on retro-reflection from the eye, to shut off a laser source in a short time to avoid approaching the hazard level of the eye. In the event of an accidental direction of laser light toward a nearby eye, the system rapidly collects and detects laser light that retroflects from the retina of the eye. Upon detecting the retroflected light, a comparator/processor assembly signals to switch off the laser source to terminate the hazard to the eye.
